Abstract: RNA aptamers are disclosed with distinct fluorescent properties, fluorophore binding affinities, and salt dependence. Also disclosed are corresponding fluorophores, with selected fluorophores evidencing high cellular permeability. The aptamer's high fluorophore affinities, the high brightness of the bound complexes, and their thermal and salt stability, provide distinct aspects of the disclosed aptamers.

Abstract: The present invention relates to a method for capturing a molecular target present in the aqueous phase of a water-in-oil emulsion, said method being based on the use of a binding system comprising (a) a surfactant bearing a functional moiety on its hydrophilic head group and (b) a chemoprobe that acts as a molecular staple between the functionalized surfactant and the molecular target and comprises at least two distinct domains namely (i) at least one capture moiety which is able to specifically bind the molecular target and (ii) at least one binding domain which is able to interact with the functional group of the surfactant through covalent or non-covalent interactions, directly or through a binding intermediary.

Abstract: The present invention relates to a new method of labelling any target molecules from a plurality of entities, preferably in high throughput regimes, i.e. allowing the analysis of several thousands of entities per run, while preserving the integrity of the single-entity information. This method is based on a tandem molecular barcoding in which all molecular targets are labelled with a first unique barcode which is different for each molecular target from an entity, and with a tag sequence coding the entity from which the molecular target originates. Once this tandem barcoding is performed, the absolute quantification of all molecular targets with a single-entity resolution may be carried out in a single run of next-generation sequencing.

Abstract: Surfactants (e.g., fluorosurfactants) for stabilizing aqueous or hydrocarbon droplets in a fluorophilic continuous phase are presented. In some embodiments, fluorosurfactants include a fluorophilic tail soluble in a fluorophilic (e.g., fluorocarbon) continuous phase, and a headgroup soluble in either an aqueous phase or a lipophilic (e.g., hydrocarbon) phase. The combination of a fluorophilic tail and a headgroup may be chosen so as to create a surfactant with a suitable geometry for forming stabilized reverse emulsion droplets having a disperse aqueous or lipophilic phase in a continuous, fluorophilic phase. In some embodiments, the headgroup is preferably non-ionic and can prevent or limit the adsorption of molecules at the interface between the surfactant and the discontinuous phase. This configuration can allow the droplet to serve, for example, as a reaction site for certain chemical and/or biological reactions.
